The present invention teaches a hair straightening system including formulations that will safely and effectively straighten curly hair for at least 2-3 months after a single application, despite frequent washings of the hair. Methods for obtaining said formulations are disclosed. Hair straightening systems including shampoo and one or more conditioners are also provided.

The present invention provides a composition that comprises at least one peptide with a sequence length of 6-12 amino acids, where 2-5 of those amino acids are cysteines for the treatment of the hair, including animal and human hair, without the use of chemicals harmful to the hair fiber and consumer health and uses of said compositions in shampoo, lotion, serum, cream, conditioner, foam, elixir, oil, aerosol or mask.

The present invention relates to a process for curl-relaxing and/or straightening keratin fibres, such as the hair, which comprises the application to the fibres of one or more compositions comprising reducing agents, one or more compositions comprising organic solvents and a step of heat treatment of the fibres by means of a heating tool.

The invention also relates to the use of the composition(s) comprising reducing agents and of the composition(s) comprising organic solvents in a process for curl-relaxing and/or straightening keratin fibres.

Finally, the invention relates to a multi-compartment device or “kit” that is suitable for performing such a process.

The present invention relates to novel hair treatment materials, and in particular materials for shaping hair and/or strengthening the hair. Also described are the use of these compounds in hair care formulations for shaping, straightening, strengthening or treating the hair, and the use of the compounds for hair straightening and/or hair strengthening.

The present invention is a versatile cosmetic composition in form of a liquid concentrate which is useful as additive or ingredient for conventional keratin fiber treatment compositions. It can be used as ready to use additive to conventional yet damaging treatments to which it is added at the time of the treatment. Such treatments are typically hair bleaches, hair colorants or permanent wave compositions. The concentrate comprises a combination of ingredients intended to reduce damage during treatments and/or to prevent undesired deposits on fibers. Such a composition comprises at least a thiol and a polymer or copolymer comprising cystine units. Such a composition is further useful as additive or ingredient for a keratin fiber caring or repairing composition to reduce damage caused by prior treatments and/or reduce undesired deposits on fibers by using the concentrate directly after treatments causing such deposits.

The current application discloses a composition that comprises at least one peptide with a sequence length of 6-12 amino acids, where 2-5 of those amino acids are cysteines for the treatment and cosmetics of animal hair, in preference human hair. There are several hair styling methods that involve breakage and reestablishment of disulfide bonds, allowing relaxation and straightening of the hair. However, the most effective methods currently used to modulate hair contain harmful chemicals. Thus there is a constant demand for formulations that efficiently model the hair fiber without damage. Thus, the present invention aims to provide a composition for treatment of the hair, including animal and human hair, without the use of chemicals harmful to the hair fiber and consumer health and uses of said compositions in shampoo, lotion, serum, cream, conditioner, foam, elixir, oil, aerosol or mask.
